optID: Int32

an int identifying the option to fetch

Returns

Object

the value of the option

Attributes: RegisterAttribute

Remarks

Fetch the value of an option. Binary options will return java.lang.Boolean.TRUE if enabled, java.lang.Boolean.FALSE if disabled, e.g.: <BR>

SocketImpl s;
            ...
            Boolean noDelay = (Boolean)(s.getOption(TCP_NODELAY));
            if (noDelay.booleanValue()) {
                // true if TCP_NODELAY is enabled...
            ...
            }

For options that take a particular type as a parameter, getOption(int) will return the parameter's value, else it will return java.lang.Boolean.FALSE:

Object o = s.getOption(SO_LINGER);
            if (o instanceof Integer) {
                System.out.print("Linger time is " + ((Integer)o).intValue());
            } else {
              // the true type of o is java.lang.Boolean.FALSE;
            }
